1.)An op amp requires the design equation Vout = 5Vin & 2Vref + AgVg. What is the value of Ag?
2.)The voltage dropout of a voltage regulator is 1.6 V. If a 16 V output is required, what is the minimum regulator input voltage?
3.) An H-bridge allows a 4 A current pulse to the drive motor. What is the average current if the duty cycle is 25% and the pulse frequency is 2 kHz?
4.) Why are capacitors used on voltage regulators?
Design a 4-bit binary incrementer using HALF-ADDERS as building blocks. The circuits implements A+1=S where A and S are 4-bit binary numbrers. The circuit has 4 inputs A3A2A1A0 and 5 outputs : S3S2S1S0 and overflow C4. Draw the circuit diagram wit..
The magnetic tape recorder uses linear analog to digital encoding. Telephone systems use non linear analog to digital conversion. Explain the difference.
A three-phase, 2000-kVA, 12-kV, 1800-rpm synchronous generator has a synchronous reactance of 20 ohms per phase and negligible armature resistance.a. The field current is adjusted to obtain the rated terminal voltage at open circuit.
Three screws are drawn at random from a lot of 100 screws, 10 of which are defective. Find the probability that the screws drawn will be nondefective in drawing (a) with replacement, (b) without replacement.
what is the new resistance level of a copper conductor wire if the lenght is changed from 200 ft to 400 ft, the area is changed from 50,000 CM to 0.10 in ^2 and the original resistance was 7 ohms
Discuss how the angle of the incident light affected the solar cell? How could solar cell designs and/or installations be designed to counter this affect?
The Hamming distance between two bit strings of the same length is the number of positions in which the strings have different bit values. For example, the Hamming distance between 1110 and 0101 is 3.
A light comes on in a storeroom when either (or both) of two doors is open. 1. What logic function is most suitable for this operation 2. Draw a circuit to represent each function using a logic gate
A GaAs device is dopeed with a donor concentration of 3*10^15 cm^-3, For the device to operate properly, the intrinsic carrier cconcentration must remain less than 5 percent of the total electron concentration.
Construction of different types of power transformer, significant energy savings
Show the design of a 2-1 Mux: (a) using a NAND/NAND implementation, (b) using a NOR/NOR implementation. Which would you prefer to build and why Assume that you have all variables and their complements available.
20 SI fibers, 2 km long each, are spliced together for a 40 km link. Each fiber has a loss rate of 1-dB/km and a numerical aperture of 0.24. Each splice adds 0.5 dB of loss. A laser diode has a threshold current of 10 mA and emits at 3 mW/mA rate.
